I thought I'd just collect some gems gathered from the case (and the thread).
1) If someone follows you and generally acts like a jerk you're fully justified in attacking them. Even getting their gun from them and shooting them (thanks Lefty).
I'm sorry, but responsible gun owners don't chase down people and ask rude questions just because they're black and wearing a hoodie. And yes, if you chase me down and demand questions, and even act like you're going to grab me, then we're fighting. And if you do this, and I see that you have a gun, then I'm going to go for your gun. Because you have a gun.
Don't people know how to behave? Chasing after people is asking for trouble. What's so hard to understand about that?
2) It's OK to constantly use a mugshot when discussing Zimmerman the burly white paranoid watchdog, and drag his every past deed through the microscope of public opinion; but Martin the 17 year old black boy who was carrying candy must be depicted only through wholesome photos that depict him younger and innocent looking, and his past deeds are sacrosanct and must never be examined.
This seems like a complaint about using publicly released photos. This is a good idea, since if you follow it, you won't humiliate yourself like many right wing sites did by posting a picture of an obviously irrelevant black kid posing in his bedroom, and then claiming that it was Trayvon Martin.
3) Police officer statements are not to be trusted, but kinda-sorta witnesses with changing stories KNOW.
In this case, the police aren't trusted because they've already made several false or contradictory statements.
4) Your lawyer appealing for sympathy is sleazy, but a country wide campaign with marches and politicians on-board is peachy
Huh?
5) If you're half white but President you're actually black. If you're half Hispanic and shoot a kid you're actually white
Well, no. Hispanic is not a racial group at all, and people with black ancestry have been considered black in the US for well over a century now. So, if you're half hispanic, then that says nothing about your race no matter what, and if you have a,black parent, then you're black, no matter what.
Don't like it? Hop into your TARDIS and get to work.
7) If someone beats you badly enough to cut your head and make your nose bleed, it better be a gaping wound and a broken nose or else they don't count
Well, yes, you don't get to Shoot and kill someone over a scuffle..
9) Teenage males who's family has broken up can not be aggressive and reckless.
It's more that black teenagers aren't all cartoonish supervillains.
